A member of the family found the couple's bodies after stopping by their Pennfield Drive home Friday. Police said they went to the house after being unable to get hold of them over the phone Thursday night.

Police said Ryan Coles was in the house when they arrived. He was taken to a nearby hospital for evaluation and later charged in the deaths. He was placed in Salem County Jail Saturday on default of $1 million bail. It's not clear if he has retained an attorney.

An autopsy performed Saturday determined the couple died from blunt head trauma and their deaths were ruled a homicide.

Edward, 58, and 55-year-old Rosemarie Coles formerly owned a well-known music store — Coles Music Service — in the community.
